Reuse of secondary aluminum ash: Study on removal of fluoride from industrial wastewater by mesoporous alumina modified with citric acid
Highlights • Synthesising mesoporous alumina with secondary aluminum ash for the first time. • Modification with citric acid increased hydroxyl radical on the surface of the material. • The removal efficiency remains above 98.20% after 5 cycles. • The maximum adsorption capacity for fluoride ions was 117.98 mg g-1. Abstract Longitudinal loading of citric acid […]

Hydrometallurgical stepwise separation of alumina and recovery of aluminum fluoride from waste anode cover material of aluminum electrolysis
Abstract Anode cover material holds marked importance owing to its effect of maintaining the thermal balance of aluminum reduction cells, and is categorized as solid waste because of its continuous accumulation. However, cover materials contain large amounts of alumina and fluoride; thus, can be considered for strategic resource recovery. This research has developed a process […]

Management of Solid Waste Containing Fluoride—A Review
Abstract Technological and economic development have influenced the amount of post-production waste. Post-industrial waste, generated in the most considerable amount, includes, among others, waste related to the mining, metallurgical, and energy industries. Various non-hazardous or hazardous wastes can be used to produce new construction materials after the “solidification/stabilization” processes. They can be used as admixtures […]
